Subject: Re: [Aroid-l] Amydrium or Rhaphidophora
Hi Helmut,
The differences (leaving aside the generic ovary/ovule & fruit/seed
differences) are:
Epipremnum pinnatum
Foliage leaves at more-or less one at each node.
Leaves with pin-holes along the mid-rib.
Shoot apex with matted fibrous material
Stems with irregular longitudinal crests.
Rhaphidophora decursiva
Foliage leaves scattered and interspersed bu up to 7 nodes bearing only a
cataphyll.
Leaves without pin-holes along the mid-rib.
Shoot apex without fibrous material.
Stems without irregular longitudinal crests.
Very best regards
Peter

Hi Peter,
Can You tell me the difference between Raphidophora decursiva and Epipremnum
pinnatum.
I have somme huge plants of this type in my greenhouse and the leaves are up
to 6 ft (2 meters) long.
My original plant is a huge climber - I think the only really big one in
Europe - in the HBV (Vienna Botanical Garden).
To my knowledge it always was presented there as Epipremnum pinnatum.
In the history of the identification of E. pinnatum You find a lot of
taxinom. changes.
Can You, Peter, as the expert, bring clearness ?
rgds. Helmut
